How often to start engine

[bcgreen]

I have a 911 SC that will be sitting around waiting for the next show and I am wondering how often should I take the car out for a run so I don't develop any leaks?
Thanks

[Alan Lindquist]

And risk going through a puddle or getting a rock chip? Are you crazy?

[bcgreen]

Its not a trailer queen, or show winner, but who knows, it just might in its class even if its not concourse.

Daily....

BCGreen - sorry for my cynical answer. You don't deserve it. I was just having fun. Post some pictures of your car. We'd love to see a nice clean SC. Mines a daily driver and it shows the 250K miles that are on it. It's nice to know that some of the SCs are being preserved and cared for as opposed to being run and rebuilt.

My guess is that the more often the better. Just choose nice days - get it up to full operating temperature and row through the gears a few times with peaks at a moderately high RPM. Stay way back from other cars to avoid road rash.

I'm thinking that you should do this as often as you can.

As often as is possible. You may want to get a bra on the car to prevent chips, being careful not to let the bra itself rub paint.

I've got a bra with driving light covers and maybe even flag mirror covers. I'd be glad to let it go for a reasonable price that's a fair deal for the buyer. PM me if interested. I'm not going to use it. It's just packed away in a box.

Maybe a clear bra, ehh?

No harm taken. I will see about posting, but it might be a while, but I will post it I promise. I have to review my notes on how to post a picture. OBTW this is a '76 2.7 all original, except for the paint.
I figure, early on a Sunday morning, just to get it up to operating temp.
I just don't know how long to go between. Is once a month not enough, if not how often?

I would suggest once a week, you could probably go a bit longer though maybe two. I believe that is frequent enough to avoid many of the issues the arise from long term storage i.e. leaking seals, flat spots on tires, low battery, etc.

As already mentioned it is important to get up to the stable operating temperature and I would suggest at least 10 mins of driving after that.

Would like to see some pics of the car if you can post some

What happens when one goes on vacation and it is longer than 2 weeks?

[Hugh R]

Agreed at least once every week or two. Let it get up to operating temp. I run my Honda 2000 watt generator for 15 minutes with my wife's hair dryer as a load once a month. I have several friends who have Yamaha or Honda generators that they let sit for six months and found the fuel system to be all gummed up, and wouldn't start.

Two weeks sitting no problem. Its not running for months, or years where you risk problems. I read all the time about people who have p-cars that sat for years without starting, but could be started, but didn't. I have to wonder why. Fuel turns to varnish, seals dry out and they start to leak. What's the big deal of going out and turning a key every once in a while?

Tires go to crap just sitting in one spot for months. I have lifting scissor jacks on my camping trailer, and I take the load off of the tires whenever I park it. It does wonders to prolong the life of the tires. I use it a few times a year. Same with the pcar, drive it to flex the tires and keep them round.

a sc ? Where does the car reside? Climate is an issue.

Exception like vacations are fine to not run the car. When I was gone for over a month I lifted the car up on jacks so the weight was off the tires. I'd hate to have to buy replacements for my Michelin PS2 before they wear out. I also disconnected the negative battery ground so the battery stays charged. All cars will draw a small amount of current. At 4 weeks my battery will be too low to start and if this happens several times battery life can be significantly shortened.

...that is likely not an SC, but rather a mid year car. Do not start it more than necessary it is not bullet-proof.

Thanks for the tip on the battery.

This is a 1976 911 SC or also known as a Carrera. Almost the last one on the line, of 123 cars.

[bcgreen]

I now realize that the car will be sitting in a container, as it is being transported to my location, for about 33 days, so hopefully nothing will have dried out before I get to it.

Thanks for preserving what sounds like a special car. Sorry you will be missing out on the fun of driving and enjoying it that way. Maybe you have another Porsche to drive?

What about fuel stabilizing? If you drive very rarely won't the fuel go off while sitting for so long?

Should the tank be topped off with fuel treatment added? To avoid rust in the tank. Or kept with very little fuel in the tank so the fuel will be used up and replaced more often?
Interesting challenge. There are others here with show cars, curious what they do in this regard.
